Background: It is challenging to simultaneously conduct total endovascular repair and reconstruct the left subclavian artery (LSA) and isolated left vertebral artery (ILVA) in patients who had an ILVA and required zone 2 anchoring. This pilot study reported the initial application experience of thoracic endovascular aortic repair (TEVAR) with a proximal zone 2 landing for aortic arch reconstruction in patients with ILVA.
Methods: This study was a retrospective consecutive single-center case series analysis, which involved four patients with ILVA who required zone 2 anchoring and received TEVAR combined with a single-branched stent graft and concomitant on-table fenestration between March 2021 and December 2022.
Results: The postoperative follow-up period was 6-27 months, and no postoperative deaths or other primary complications occurred. There were no signs of a stroke or spinal cord ischemia, as well as no chest or back pain. The postoperative computed tomography angiography showed unobstructed ILVA and LSA, no stent stenosis and displacement, and no signs of endoleak.
Conclusion: The outcome suggested that this technique might be a feasible, safe, and alternative treatment for such patients. Further studies with larger samples and longer follow-up periods are needed to confirm our findings.

Modified Ex Vivo Renal Reconstruction to Facilitate Fenestrated-Branched Endovascular Repair of a Thoracoabdominal Aortic Aneurysm.

Article Synopsis
- The report discusses a surgical technique called modified ex vivo renal artery reconstruction used in a patient with two small right renal arteries, as part of a staged hybrid repair prior to a planned endovascular aortic repair for a thoracoabdominal aortic aneurysm.
- The initial surgery involved creating a hepato-renal bypass using a saphenous vein graft to link both small right renal arteries, followed by a second stage that utilized a custom stent-graft to address the main arteries affected by the aneurysm, successfully preserving kidney function.
- The case highlights the advantages of hybrid surgical methods in managing complex vascular issues, particularly how the modified ex vivo technique enables precise reconstruction of renal arteries

Background: Total endovascular technique with fenestrated endovascular graft might be hampered for the late dilatation of proximal landing zone, which may cause endografts migration. We describe a successful urgent hybrid procedure for extent III thoracoabdominal aortic aneurysm with aortic intramural hematoma.
Case Presentation: A 55-year-old female with thoracoabdominal aortic aneurysm was considered at high surgical risk and unfit for open repair due to multiple comorbidities.

Objective: This study aims to evaluate the feasibility, efficacy, and safety of a single-branched stent-graft with on-table fenestration for primary retrograde type A aortic dissection (RTAD) during thoracic endovascular aortic repair (TEVAR).
Materials And Methods: From January 2019 to December 2021, 36 patients with primary RTAD from five tertiary hospitals received medical management in the acute phase. They underwent TEVAR with a proximal zone 1 landing for aortic arch reconstruction in the subacute phase, using a fenestration technique on a single-branched stent-graft.
